I don't see how the phrase 'Bad Thing' alone is a copyrightable work. And even if it was (say, it was typeset in a particular fashion, or part of a greater work), registration would be unnecessary.

Sarcastic use of the trademark (™) and registered trademark (®) symbols is a common rhetorical device, but copyright doesn't make much sense. The "intellectual property" propagandists do their best to confuse people into thinking that copyright, trademarks and patents are the same thing, perhaps that's why you're confusing the two?
